AD9629:  12-Bit, 20/40/65/80 MSPS, 1.8 V Analog-to-Digital Converter

Product Description

The AD9629 is a monolithic, single channel 1.8 V supply, 12- Bit, 20/40/65/80 MSPS analog-to-digital converter (ADC), featuring a high performance sample-and-hold circuit and onchip voltage reference. The product uses a multistage differential pipeline architecture with output error correction logic to provide 12-Bit accuracy at 80 MSPS data rates and guarantees no missing codes over the full operating temperature range.

The ADC contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable digital test pattern generation. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI). A differential clock input controls all internal conversion cycles. An optional duty cycle stabilizer (DCS) compensates for wide variations in the clock duty cycle while maintaining excellent overall ADC performance.

The digital output data is presented in offset binary, Gray code, or twos complement formats. A data output clock (DCO) is provided to ensure proper latch timing with receiving logic. The AD9629 is available in a 32-lead Pb-free LFCSP and is specified over the industrial temperature range (−40°C to +85°C).
